Enta (Japanese: エンタ Enta) is a recurring character in the Pokémon anime. He is the mayor of Hearthome City and serves as an announcer for several Pokémon competitions within the city. He first appeared in Tag! We're It...!.
Enta made his debut appearance in Tag! We're It...!, where he was seen welcoming Tag Battle Trainers to Hearthome City. He revealed he would host the Hearthome City Tag Battle Competition and then explained the proceedings to all the contestants and the audience. He asked the competing Trainers to check their registration cards and use the numbers as a guide to find their Tag Battle partners, which had been randomly decided.
After everyone had located their partners, he announced that the winning team would receive two Soothe Bells, one for each Trainer. He also said the competition would only start later that day, advising Trainers to practice in the meantime. When the competition really began, Enta explained the rules, saying that each Trainer was allowed to use one Pokémon, substitutions were prohibited, the battles had no time limit, and whichever team ended up unable to battle would be eliminated. He also provided commentary during the competition.
He appeared again in Glory Blaze!, where he continued to comment on the battles and announced the semifinalists of the event. He made his next appearance in Smells Like Team Spirit!, where he was seen handing out the two Soothe Bells to Ash and Paul as their prize for winning the Hearthome City Tag Battle Competition, after they defeated Dawn and Conway in the final round.
He returned in Arriving in Style! to host the Hearthome Collection, a fashion show for Pokémon Stylists whose winner would get the chance to work on a photo shoot for the Poké Chic magazine.
Enta appeared briefly in a flashback in Playing The Leveling Field!, where he was shown along with Fantina in the inauguration of the Hearthome Gym.
Enta is a very active kind of person who likes to be involved in the Pokémon competitions taking place in Hearthome City. He seems to enjoy working as an announcer, as he is always excited when giving a running commentary of an event, so much so that his lively attitude annoyed Jessie during the Hearthome City Tag Battle Competition.
